That's what I cut in my Crown Vic with a T5, open 3.08, 5.0 with Exploder top end, and aluminum flywheel. Thing was a b*tch to launch and they shut us down for wind before I could figure anything out. It ran a 15.9 here, so would have been a low to mid 14 at sea level with a competent driver. It later got 3.73 and a posi and I so regret not running it again like that.

Only worried about the launch right now, power shifting comes later.
What tires do you suggest if the M&H Racemasters aren't good enough?
I am guessing massive wheel spin at launch in the 1/4. My favorite at the track, unfortunately the closest is 4 hours away now, was a new Camaro running a 10.6 in the 1/8🤣. I love the pics on the road course, it looks like the sheer mass of the Hellcat is flattening the cones as it draws near them.
If you're overpowering the tires with that low rpm launch which isn't even into boost yet, I gotta believe a tire that hooks will allow a more aggressive leaving of the line and thus, better 60'.
I get that you wanna use the DR's but soon your head will explode when the reality is that it's spinning them.

There is no boost because TC is turned off and that cuts "torque reserve", I covered that a few pages back.
I am not a throw money at it kind of guy - but, I am willing to listen. So what tire magically fixes this condition? I am looking into 17" softwall slicks at the moment - assuming I can find one that suits the car.
For reference: The run before this one I obliterated the tires with different settings. Look at the throttle mapping.
So I dialed it back and tried to find a compromise between bog and spin. It didn't happen.
My guess is I am going to have to habitually slip the clutch through the whole 60 feet. This concept is counter intuitive to me.
My suggestions are only because I'm trying to help with lowering the E.T. and not trying to be critical of your approach.
I'm no tire expert and don't have a magical solution when it comes to the right choice.

I get that, and I got a LOT of "socially distanced" advice at the track yesterday too. While I do believe there is something to be gained in having a proper slick on a stick car to absorb the shock of a proper hard launch - I am still mostly convinced that the problem lies in my abilities at this stage. I would almost be better off with a more basic stick car to practice on - this is like trying to do quantum physics with a marginally functional understanding of BEDMAS.
If you look at the graph above it was leaving with 300+ft/bs of torque, and the airflow comes in almost instantaneously. I'd rather it feed it progressively to meet the needs of the chassis and the track. Oh, and the limitations of the driver.
